UNITED PATENT orricn mm s. or mimosa, MABJYLAND.J

Be it known that I, HENRY S. Bimwms- TON, a citizen of the vUnited'states, residing V at Baltimore city, State of Marylanth'have invented certain new and useful vImprovements in Register-s for Telephone-Calls,v of

which the following is a specification.

Thisinvention relates to means for registering the number of calls made by the users of telephones. I Many disputes have arisen over the bills rendered subscribers by telephone companies for calls made on their telephones and as yet there has appeared in public no device which will satisfactorily register the number of such calls. A register at the exchange, actuated by the operator, would be unsatisfactory to the subscriber, and a register at each telephone, operated by the subscriber would be equally unsatisfactory to the company. The primary objectof this invention is to overcome the existing troubles, and to de stroy all chances for disagreement over the matter. v

A further object of this invention is to provide a register for the purposedescribed, to be actuated by the operator but at the samte time be under the control of the sub sci-1 er.

further object of the invention is to provide a register of this character with means, under the, control of the subscriber, whereby the operator will be permitted to actuate the mechanism.

A further object of the invention is. to provide .a register, at the telephonefopen able only-by the operator at the exchange, and operable by the o erator at the exchange only when the su scriber atthe'telephone has necessarily adjusted the mechanism to permit of-suchoperation.

With these and other objects in view,;the invention consists in the improved construction, arrangement andcombination of parts hereinafter fully described and afterward specifically claimed. 7

' In order that the-construction and operation of the invention may be readily com prehended,I will now specifics-ll. describe the same, in connection with t e accom panying drawings, which illustrate a preanezsran For, munitions-earns.

To all whom it may concern: ferred embodiment of the invention, and in which- Fi re 1' represents a front elevation of a. telep one'equ pped withmy improved register, the caslng of the latter being partially broken away to expose the interior mechanism. v Fig. 2 represents a vertical sectional View taken on the plane indicated by the broken line 2-2 of Fig. 1, Fig. 3 represents, diagrammatically, the immediate connections with the telephone hook, the latter being shown in side elevation and in a neutral position, Fig; 4 represents diagrammatically the arrangement of the parts with reference to the circuits, the hook being in neutral position, Fig -5 represents a view similar to Fig. 4, with the hook raised and i in operative position.

Llke reference characters 7 indicate 1 the same ings. I

Referrin 'specifically'to the drawings, 10 indicates t e standard, 11 the transmitter parts in all of the'figures of the draw ,and mouth piece, 12 the hook, 13 the re-' ceiver, and 14; thecable containing the wires leadingto the receiver, all of which parts may be of any suitable well known construction.

At 15 is shown a casing, of any suitable lsize, s'hape and material, in which I house the operative mechanism of my invention,

suchcase being supported, at the subscribers telephone, 1n any su table manner, be

from the standard 10 of the .telephone to which it may ably, in any suitable manner.-

Within the casing 15 are journaled a plurality of shafts of any desired number, here in shown as three in number, marked 17 18 and 19, geared together so'that one revolution of 17 will rotate 18 one step and one.

ing here shown as supported on a bracket 16 be secured, preferably removany suitable manner to the casing 15, as for instance by screws, is a bracket 24 in which is slidably mounted a rod 25 secured to or formingpart of the armature 26 of an electromagnet .27, from which rod 25 projects a pin 28 connected by a spring 29 with a hook 30 secured to a wall of the casing; When the electro-magnet 27 is energized, as hereinafter explained, the armature 26 will be attracted to it,-drawing the rod '25 with it, against the stress of the spring 29, when, by reason of the engagement of a hook 31 on the end of the rod with the teeth of the ratchet wheel 23, said Wheel will be rotated one step, which step will duly register on the dials, in a manner well known, the specific construction bf the registering wheels and dials forming nopart of the present invention.

One step will be made and one registered for each call made on the telephone by means of the devices and arrangements now to be described.

Referring particularly to Figs. 3 to 5 of the drawings it will be observed that the hook 12 is pivoted on its pin 32 in the usual manner and'besides the-usual contact arm 33 which projects downward inside of'the box, there is provided an upwardly projecting contact arm 34.

In Figs. 4'and 5 I have illustrated dia-- grammatically the usual circuits, supplemented by the circuits necessary for the operation of the present invention, said usual circuits comprising a wire 35 from the exchange, where there is any usual circuit closer, switch, or button 36, saidwire extending to a post 37, thence to, as at 38, a terminal or contact 39 adjacent to the usual contact arm 33 of the hook which latter connects said contact point or terminal with anothercontact terminal 40 when the receiver is ofi the hook,'as inFig. 5, from which point 40 the wire extends as at 41 to the receiver 13 and thence, as at 42 to and through the condenser 43 and finally, as at 44 returns to the exchange. A second usual circuit is formed when the, receiver circuitis closed,-as in Fig. '5, and comprises wire 35 and 36, contact terminal 39, contact arm 33, hook 12,.pin 32, wire 45, transmitter 11 and wire 44 back to the exchange, being the transmitter circuit. A third usual circuit comprises wires 35 and 46 to the bells 47 and thence by wires 48 and 49, condenser 43 and wire 44 back to the. exchange. A fourth circuit includes wire .35, post 37, wire 50, electromagnet 27, wire 51, contact 52, which when the receiver is. off the hook, as in Fig. 5, touches contact 53 from which the circuit extends through wires 54, 48 and 49, and through the condenser 43 and wire 44 back to the exchange. When a call is made by a subscriber, the parts being as indicated in Fig. 4, the receiver is removed from the scriber, thus giving himnotice by both bell and dials that a call has been registered,

It will be obvious that only the bell circuit can be closed while the receiver is on the hook so that while only the operator at the exchange can put the registering mechanism in operation, such action cannot be made unless permitted bythe subscriberby removing the receiver from the hook, and further no registering can be performed, even when permitted by the subscriber with out making an ocular and an aural demonstration thereof. 1

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States- 1. In a telephone system, a ringing circuit subscribers talking circuit is closed, where'- by said bell will. ring continuously while said registering mechanism is being actu ated.

2. In a telephone system,'a ringing circuit including a bell and a condenser, a registering circuit including a registering dial, an armature for operating said dial and an electromagnet for controlling said armature, said registering circuit being in parallel with said bell and in series with said condenser, and means at the exchange end of said circuits for controlling said ringing circuit while the subscribers talking circuit is open and controlling both said ringing and register circuits when said subscribers talking circuit is closed, whereby said bell will rln continuously while said registering mec anism is .being actuated.

3. In a telephone system, a ringing circuit including a bell and a condenser, a registering circuit including'a registering mechanism in parallel with said bell and in series with said condenser, and means at the exchange end of said circuits for controlling said ringing circuit while the subscribers talking circliii', is open and controlling both In testimony whereof I aflix my signature said ringlng and registering circuits when in presence of two-witnesses. said subscribers talking circuit is closed,

whereby said bell will ring continuously HENRY BREWINGTON' while said registering mechanism is being Witnesses: actuated, and a receiver hook for closing SAMUEL W. KIRK,
